IMPORTANT SERVICE NOTES 21L-FG1SA/SF/SM/RU [1] IMPORTANT SERVICE NOTES Maintenance and repair of this receiver should be done by qualified service personnel only. 1. SERVICE OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE When servicing the high voltage system, remove static charge from it by connecting a 10K ohm resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.) 1) Picture tube in this receiver employs integral implosion protection. 2) Replace with the same type number of picture tube for continued safety. 3) Do not lift picture tube by the neck. 4) Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely. 2. X-RAY This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed: 1) When repairing the circuit, please make sure do not increase the high voltage of the set to more than 30.0kV (at beam 0µA). 2) To keep the set in a normal operation, please make sure it s function at 26.8kV ± 1.0kV (at beam 1,100µA). The set has been factory - adjusted to the above-mentioned high voltage. *If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work. 3) Do not substitute a picture tube with unauthorizerd types and/or brands which may cause excessive X-ray radiation. 3. BEFORE RETURNING THE RECEIVER Before returning the receiver to the user, perform the following safety checks. 1) Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver. 2) Inspect all protective devices such as non-metal control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators etc. 2 1

ADJUSTMENT PRECAUTIONS [1] ADJUSTMENT PRECAUTIONS This model's setting are adjusted in two different ways: through the I2C bus control and in the conventional analog manner. The adjustments via the I2C bus control include preset-only items and variable data. CAUTION: Make sure TV set in "Normal condition" before switch to Service Mode for adjustment. 1. Setting the service mode by the microprocessor. i) Power OFF the TV set. Press both CH-UP and VOL-DOWN on the TV set and then turn on the Main Power simultaneously. Wait for 5 seconds, the TV will switch to Service Mode and the micrprocessor is in input mode. (Adjustment through 12C bus control) Service mode also can be reached by pressing Service key (code: 81 Hex) ii) Press the MENU key on the remote controller to get ready to select the mode (Adjustment mode, Setting mode, Check mode and Option mode) one by one. iii) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment mode, Setting mode or Option mode. iv) Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified. Please wait approximately 200 msec for data storage in EEPROM before select to another mode. v) In Check mode the data cannot be changed. vi) Press both CH-UP and VOL-DOWN buttons on the TV set simutaneously or press the SERVICE (81 HEX) key again, it will switch to the NORMAL mode position, and the microprocessor is out of the SERVICE mode. 2. Factory Presetting. i) During Service mode, press both CH-UP and VOL-UP on the TV set simultaneously fro 5 seconds. Then release the CH-UP and VOL-UP button. Initial values are preset. ii) The initial data are preset as listed in page 3-7 to iii) Make sure the data need modification or not (Initial data). Precaution: If haven't done this initialization, it may possibly generate excessive Beam current. 3. For reference please check with memory map RH-IXB725WJN1. (See Page 4-1 ~ 4-16) 3 1

DISCONNECT THE AC PLUG FROM THE AC OUT- LET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE RE- GARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING. NOTES: 1. The unit of resistance "ohm" is omitted. (K = 1000 ohms, M = Mega ohm). 2. All resistors are 1/16 watt, unless otherwise noted. 3. All capacitors are µf, unless otherwise noted. (P = µµf). IMPORTANT SAFETY NOTICE: PARTS MARKED WITH " " ( ) ARE IMPO- TANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECI- FIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET. VOLTAGE MEASUREMENT CONDITIONS: 1. Voltages in parenthesis measured with no signal. 2. Voltages without parenthesis measured with 3mV B & W or Colour signal. 3. All the voltages in each point are measured with VTVM. SERVICE PRECAUTION: THE AREA ENCLOSED BY THIS LINE ( - ) IS DI- RECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLAT- ING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK. WAVEFORM MEASUREMENT CONDITIONS: 1. The colour bar generator signal of 1.0V peak applied at pin (41) 32 of IC Approximately 4V AGC bias.
